Discover why sand is crucial beneath pavers. Learn about proper base preparation for durable, long-lasting paver installations.
Do I Really Need Sand Under Pavers?
When planning a paver project, it’s common to question the necessity of each layer involved. One such layer is the sand bedding beneath the pavers. While it might seem like an area to cut costs or effort, the sand layer plays a pivotal role in the longevity and stability of your paver installation.
Understanding the function and benefits of this sand layer can help ensure your project stands the test of time.
The Role of Sand in Paver Installations
The sand layer, often referred to as the bedding layer, serves multiple essential purposes in a paver installation:
Leveling Surface: Sand provides a smooth and even surface, allowing pavers to be laid uniformly.
Drainage Facilitation: It aids in water drainage, preventing water accumulation that can lead to paver displacement.
Flexibility and Support: Sand accommodates minor shifts in the ground, reducing the risk of pavers cracking or breaking.
Skipping this layer can compromise the structural integrity of your paver project, leading to issues like uneven surfaces and increased maintenance needs.

Choosing the Right Sand for Your Project
Not all sands are created equal, especially when it comes to paver installations. The type of sand used can significantly impact the durability and appearance of your project.
Concrete Sand: This coarse sand is ideal for the bedding layer, offering excellent compaction and drainage properties.
Polymeric Sand: Used for filling joints between pavers, this sand contains additives that harden when wet, locking pavers in place and preventing weed growth.
Avoid using fine sands like playground or mason’s sand, as they lack the necessary compaction and drainage capabilities, leading to potential issues over time.
Steps for Proper Paver Installation
Ensuring each layer is correctly installed is crucial for a successful paver project.
Excavation: Remove the existing soil to the required depth, accounting for the base, sand, and paver thickness.
Base Layer: Lay and compact a gravel base to provide a stable foundation.
Bedding Sand: Spread a 1-inch layer of concrete sand over the base, ensuring it’s level.
Paver Placement: Lay the pavers in the desired pattern, pressing them into the sand.
Joint Sand: Fill the gaps between pavers with polymeric sand, then compact the surface to lock them in place.
Each step is vital, and cutting corners can lead to premature failure of the installation.
Common Mistakes to Avoid
Even with the best intentions, certain mistakes can compromise your paver project:
Using the Wrong Sand: As mentioned, not all sands are suitable. Ensure you’re using the appropriate type for each layer.
Inadequate Compaction: Failing to compact each layer properly can lead to settling and uneven surfaces.
Skipping the Sand Layer: Omitting the bedding sand can result in poor drainage and paver instability.
By being aware of these pitfalls, you can take proactive steps to ensure the success of your project.
